HENRY AUGUSTUS PITCHER, OF NEILLSVILLE, VISCONSIN.

MAGAZINE-GUN.

SPECIFICATION forming part of Letters Patent No. 452,192, dated May 12, 1891.

Application filed December 5, 1890. Serial No. 373,647. (No model.)

To @ZZ whom it may concern:

Be it known that I, HENRY AUGUSTUS PITCHER, a resident of Neillsville, in the county of Clark and State of IVisconsin, have invented certain new and useful Improvements in Magazine-Guns; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same.

The obj ect of my invention is to reduce the aggregate of the frictional surfaces, lessen liability to fouling, diminish the number and weight of parts, and otherwise simplify and improve the loading mechanism of a magazine breech-loading gun; and it consists in the construction hereinafter described and pointed out.

In the accompanying drawings, Figure l is a partial side elevation of a gun with the improved mechanism. Fig. 2 is a similar view, the breech-block being withdrawn from the barrel. Fig. 3 is a longitudinal section of the same. Fig. a is a partial elevation showing breech-block locking-pin and connected parts. Fig. 5 is a transverse section on line :c @c of Fig. l. Fig. G is a plan of the carriage-holder. Fig. 7 is a like view of a modiiication. Fig. 8 is a partial plan showing the exterior and breech-block, and Fig. 9 is a longitudinal section through a cartridgemagazine holder. j

Numeral 1 indicates the barrel, 2 the stock, and 3 the hammer, of a gun.

et denotes a receiver or frame interposed between the stock and barrel and rigidly connected to both in any well-known manner.

5 is a slide or saddle form piece, the sides of which are connected by a pin or screw 6, which is adapted to be moved in a slot 7 of the receiver.

8 indicates the breech-block, which is located in the slide and moved ou the receiver, and 9 is the firing-pin within a recess or groove in the breech-block. l0 denotes a locking-bolt or T-shaped brace pivoted at l1 to the breech-block and adapted to engage a notch l2 in the receiver to lock the blockin its forward position. Adjacent to the rear end of the T-shaped brace the block is cut away across its whole width to receive the large end of the brace, which has the same width as the block.

13 is a screw or pin secured Ain the slide and movable with it, and la indicates a slot in the breech-block, which permits the slide and pin 13 to move in the block until 'said pin strikes the end of the slot., whereupon the block moves with the slide.

The slide is connected by an arm or shank 15 to a handle, which is connected to the receiver in such manner that it and the slide can be moved back and forth upon the receiver. Preferably these parts are connected in one piece.

The operation of the above-described device is as follows: The parts are in the position indicated in Fig. 2 when a cartridge is exploded. To charge another cartridge into the barrel and cock the gun, the slide is forced back by the handle. rlhe first part of the movement carries the pin 13 to the rear end of the slot 14l in the breech-block and just to the rear of the locking bolt l0, so that the latter is free to turn on its pivot, when immediately after its front end is struck by the projection 1G on the iiringpin, moving rearwardly under compulsion by pin 13, attached to the slide. The impact of projection 16 upon the suitably rounded or beveled end of the locking-bolt l0 throws the rear end of said bolt out of the notch 12, whereupon the breecli-block and iiring-pin are carried back until pin 6 strikes the rear end of slot 7. The iirst rearward movement of pin 13 acts upon the firing-pin to retract it from contact with the priming in the cartridge, and its further movement to the rear carries the breech-block with it and cocks the gun. As the breechblock is t-hus moved to the rear` it iswithdrawn from the top of the face of thercartridge-box of magazine 17, and a cartridge is forced up by the spiral spring underneath until interrupted by the side flanges on the cartridge holder or box, and it is thus placed in alignment or nearly in alignment with the barrel.

The magazine or cartridge-holder 17 (or 17) has an L-shaped follower 1S, beneath which land under the base of the cartridge is arranged a spiral spring to force up the follower IOO and the superincuinbent cartridges. The spring is held in place by ribs orr shoulders 19, formed in any convenient manner in the cartridge-holder, as indicated in Figs. 6 and 7. These ribs and the front and rear walls of the magazine are curved, as indicated.

'20 is a forwardly-turned projection on the rear of the-magazine, at its upper extremity having an edge arranged to bear on the rear end of the upper cartridge above its longitudinal axis and a little above the top of the holder to prevent the front end of the cartridge from tipping upward.

21 are side flanges or projections at the top of the holder adjacent to the cartridge head or rim, which latter extends a little above said flanges. The purpose of these devices is to maintain the proper position of the cartridge in line to enter the bore of the gun and to hold said cartridge until it is pushed into the barrel by the breech-block. Thi-s is effected by the joiutaction of the overhanging flanges or projections 21, which bear on the cartridge-rim above its horizontal center, and of the plate 20, the edge of whi-ch bears on the rear end ofthe cartridge, also above its center. The spring presses the cartridgerim against the under side of said iianges or projections 21, and they and plate 20 prevent the front end of the cartridge from tilting up, and the top cartridge is thus held in nearly horizontal position.

'lhe rear of the upper part of the magazine chamber or recess is somewhat contracted and the iianges 21 thus formed upon each side edge prevent the cartridges from slipping forward or out of the recess until pushed forward by the breech-block. The front end of each top cartridge in the recess is permitted to rise above the front end of the recess and in position to enter the barrel at all times except as hereinafter stated. The object of the transverse projection 20l at the base of the cartridge is to prevent the front end of the top cartridge from tipping upward and backward when placed upon the follower (or cartridge previously inserted) and under flange 21, and to thus hold the point of the top cartridge in position to enter the barrel at all times when the breech-block is fully withdrawn to the rear. The L-shaped follower, guided by the curved ribs and its position in the recess, brings each successive cartridge up into proper position for insertion into the barrel when pushed forward by the breechblock.

Acartridge having been raised by the spring and properly directed, as stated, it is pushed into the barrel by a forward movement of the handle and slide, which latter carries the pin 13 against the suitably rounded or beveled rear end of the locking-bolt 10 and forces it into the notch 12, at the same time Ymoving the breech-blockwhich pushes forward the cartridge. Duriu g this movement the firingpin falls behind or rests, and maysubsequentment of the slide is determined by the slot 7,

which arrests the pin 6 in either direction;

valso'that pin 13 drives forward the breechblock and also ret-racts i-t and the tiring-pin,

suitably releasing in its rearward movement the locking-bolt 10, which bolt at other times holds the breech-block in its forward position. Upon the return of pin 13 it holds the lool;- ing-bolt in engagement with the receiver and receives the recoil o-f the breech-block.

The magazine may be suspended in any suitable opening in the receiver, being slightly engaged at its top to prevent its dropping through, or said holder may be a fixture, as elsewherey described. Asprin-g 22, secu-red to the receiver, has a portion 23, Fig. 8, over the holder when in position, if removable, toll-1inder its accidental displacement. This spring is provided with aproj-ection or-stop 2l, adapted to engage the rim of the cartridge-shell above its horizontal diameter or center when it is extracted from the barrel, by which means the rear of the shell is held dow-n when its body is thrown to one side.

28 indicates a groove in the block to re- [ceive the part 23 of the spring when said block isI moved forward. The spring always overhangs the magazine to prevent it from being accidentally thrown up or O IIt of' the receiver, except when it is intentionally pulled to, one side toperinit the magazine to b e removed. The. groove in the side of the block is adapted to receive a stop 24.-. Y

2,5, Fig. 8, is the exterior, secured by a-` pin or screw 26 on the breech-block and having a hook 27, which catches the rim ofthe shell and withdraws it from the barrel when the block is moved baekwardly. l

Part of my improvements are applicable to guns having detachable magazines; but it is proposed ordinarily to make these magazines a permanent fixture free from liability to accidental displacement and other objections, and for this end the magazine may consistI of a suitable recess or mortise formed in the receiver, substantially as indicated in Fig. 9. Preferably a suitable lining made from non-corrodible material and of greater or less extentwill be iixed in such recess, such a fixed lining being permanently fastened in the receiver byscrews 4". Such a magazine will have substantially the same contour and adj uncts as the detachable magazine above described. l

To ill the receptacle it will be seen that the breech-block must first be drawn to the rear. The cartridge to be inserted is then pressed headdownward against the follower IOO ' or against the cartridge previouslyv inserted tially as set forth.

and then slid back to the rear ofthe recess.

The front end of' the cartridge is then tilted forward and downward until Ythe projections 21 and the`rear bearing20 bear against it,- as before described, when it will remain in -position to enter the barrel. The above-described constructionof the magazine provides for its being charged with cartridges without its removal from the receiver. When the breech -block is moved forward, 'it forms a cover to the cartridge-recess and holds the cartridges from rising untilagain withdrawn from the face of said recess.

Having thus described mypinvention, what I desire to secure by Letters ,Patent is 1. Inra gun, vthe barrel, the slotted receiver connected thereto, and the operating-slide pro- 'videdv'ith a handle and with a pin extending through the slot inthe receiver, 'whereby the slide and pin are guided 'and the length `of their movement determined, in combination with a firing-pin, a breech-block, and a second pinattached to the slide and engaging the firing-pin and -breech-block in its rearward movement to retract the same, substan- 2.
